3. Parameters and Register Addresses
3.1 Overview
Introduction
This section provides maps of the configuration parameters in the Herculine actuator. Using Function
codes 20 and 21 you can read and write configuration values to the actuator. The configuration parameters
are arranged according to the set up groups in which they appear when using the local display and keypad
interface.
Each parameter is listed with its register address, data format type (32-bit floating point or 16-bit integer)
and available selections.
General Information
Analog / Digital Parameters
Whenever configuration parameter values are changed via communications, a write cycle occurs after the
response is returned acknowledging receipt of the message.
